volatile | volatile | volatile : Declaring a variable volatile ensures that all threads see a consistent value of the variable. Volatile guarantees atomic reads and writes of values, however, it does not guarantee the atomicity of composite operations such as variable incrementation (read-modify-write sequence). "Operations on the master copies of volatile variables on behalf of a thread are performed by the main memory in exactly the order that the thread requested." \[[JVMSpec 99|AA.
